CENTRIFUGAL LlQUiD-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 648,665, dated May 1, 1900. Application filed May 24,1899. Serial No. 718,003. No model.

T0 all whom it 1114/ concern to it known that I, MATTHEW L. How, a citizen ofthe United'States, residing atllirchton, in the county of Saratoga and'State of New York, have invented new and useful Impro\-'cn 1ents in Centrifugal Liquid-Separators, of which the following is a specification.

This invention relates to the laminate divisioncontrivances which are placed in the liquid-space of centrifugal liquid-separators, particularly centrifugal crcamers, and which consist of numerous leaves or blades by which the body of liquid is divided into numerous thinlayers in which the separation is more rapidly and completely effectedthan when the liquid is acted upon in a single body or mass. A division contrivance of this character is described in Letters Patent of the United States granted to me January 5, 1897, No. 574,607. In the eontrivance of this patcut the blades are movably connected, so

that they can be opened out or unfolded for eleaningwhen the device is removed from the bowl and so that the outer edges of the blades support themselves against the peripheral wall of the bowl when the device is in use.

The object of the present invention is to employ in the bowl separate or disconnected blades which are ntirely detached from each other when removed from the bowl and are therefore easily cleaned, but can be readily so'placed in the bowl as to fill theliquid-space thereof and which hold themselves while in use in the proper position with reference to each other and with reference to the bowl.

In the accompanying drawings, consisting of two sheets, Figure 1 is a vertical section of the bowl of a centrifugal liquid-separator, showing the general arrangement of the blades of the division contrivance, but omitting the interlocking devices and spaceblocks. Fig. 2 is a horizontal section in line 2 '3, Fig. 1. Fig. 3 is'ahorizontal section, on an enlarged scale, of a portion of the division contrivanee, the thickness of the parts and the spaces between the blades being exaggerated to represent the parts more clearly. Figs. 4, 5, 6, and 7 are detached perspective views of different blades of the division contrivance.

Fig-S is ahorizontal section, on an enlarged scale, of a portion of the division contrivinu-c, showing the blades thereof confined by a surroundingcagc. on a reduced scale, showi g the blades held together by the surrounding cage, the interlocking devices being omitted for the purpose of simplifying the figure. Fig. W is an elevation of the cage.

Like letters of reference refer to like parts in the several figures.

A represents the bowl of a centrifugal liquid-separator which may be of any usual or suitableconstruct-ion. As shown in the drawings, the bowl is provided with the usual rcmovable cover ll, which contains the escapepipes I) for-the skiln-n'iilk and the .-rc:'un-dis charge I).

O'rcpresenis the central rcod-pirm, which projects through the neck of the cover and is provided at its lower end with feet by which the lower end of the pipe is supported at a short distance above the bottom oflhc bowl. The lowerend of the pipe is provided with an outwardly-projecting horizontal flange (1-.

E represents upright wings secured to the outer side of the feed-pipe.

F F F F',represcnt the blades or leaves of the di ision contrivance, which are arrangei'l in an upright position in the liquid-space of the bowl. These blades are arranged tangentially or eccentric around the axis of the bowl and are of such width and number that they will bear with their outer portions against the peripheral wall of the bowl and will occupy the liquidspace of the bowl cireum ferentiall y when standing at the proper distance apart. The blades are preferably curved, as shown, and arranged with their concave sides forwardly in the direction in which thebow-l 1-0- tates, as indicated by the arrow in Fig. 2. Blades arranged in this manner intersect the radial lines of the bowl and greatly expedite and improve the separation. While I prefer to employ curved blades, I do not wish to limit myself to this form, as other forms may be employed.

The blades or tachable, or separate,

leaves are disconnected, doso that when the division contrivance is removed from the bowl each plate can be entirely separated from Fig. i) is a horizontal section,

every other blade, whereby the cleaning of the blades is greatly facilitated. 'lhebladcs arc'providcd with space-blocks g of the proper thickness to hold the blades at the desired distance apart when arranged in the bowl.

ll represents interlocking pins or studswhich project from the sides of the blades and pass through corresp odingopenings hill the adjacent blades. These pins and openings are so arranged that when the blades are engaged with each other by these pins and open ings the blades will be held in the proper relative position, one slightly behind the other, or in echelon circumferentially, as shown in Fig. 3. These studs and pins form very simple and eifective intcrlockingdevices, which enable the blades to be assembled in the proper relation before being placed in the bowl and which retain the blades in this relation or'in apposition when assembled and while in use. The heads of the interlocking studs are preferably utilized as space-blocks and the opens ings are preferably formed, as far as possible,

in corresponding space-blocks, as shown in the drawings. As shown in Figs. 3,- 4, 5, and (i, the blades 1', to which pins are attached, alternate with blades 1*" F which'carry no pins; but this arrangement may be varied as may be most convenient. While these interlocking studs and openings are here applied to det-achedor disconnected blades,it is obvious that they may also be applied to blades which are movably connected. If desired, the blades may be confined, as shown in Figs. 8, f), and 10, in a foraminous jacket or cage I), of any suitable construction, which permits of the free escape of the separated skim-milk from the spaces between the blades and of the free flow of-theskim-milk upwa'rdly along the peripheral wall of the bowl.

In tln= d rawi'ngs this cage or jacket is represontcd asbeing composed of upright bars I and horizontal curved connecting rods or wires 1'.

The bars rest against theperipheral wall of the bowl and center the device in the bowl.

I claim as my invention- 1. A laminate division contrivance for cen-' tril'ngal liquid-separators consisting of an annular series of separable, tangential or eccentric blades provided with interlocking devices which 'hold adjacent blades in apposition when put ingot-her and prevent the displacement or the blades in the surface direction of the same. substantially as set forth.

2. A laminate division contrivance for'ccntritngal liquid-separators consisting of an annular series of separable tangential or eccentric-division-blades provided with 1' nterlocliing projections and openings whereby adjacent blades are held against displacement on each other, substantiallyas set forth.

3. The combination with the bowl of a c ntrifugal liquid-separator, of an annular series of upright,tangential or eccentric divisionblades which are disconnected and provided with interloekin g devices which hold adjacent blades rigidly in apposition when put together and prevent the displacement of the blades in the surface direction of the same, said blades having also spacing projections whereby the blades are held apart, substantially as set forth.

4. The combination with a laminate division contrivance for centrifugal liquid-sepavided with. interlockingstuds and openings,

the studs of one blade passing through the opening or openings in the adjacent blade or blades and retaining the blades against displacement with reference to each other, sub.- stantially as set forth 6. A laminate division contri'vancc torliquid-separators having its division-blades provided with interlocking studs and openings,

the studs ofone blade passingthrough the opening or opening in the adjacent blade or blades and retaining the blades against displacement with reference to each other, and space-blocks arranged on the blades in line with each other, substantially as set forth.-

lVitness my hand this 18th day of April, 1899.
